This invention relates to improvements in paper making machines, and hasfor its object to provide, in connection with a stock box, a breast rollwhich projects into one corner of the box and forms a part, thereof.

It is an object of this invention to provide, in connection with a stockbox, a breast roll which projects into one corner of the box andsupports a wire netting onto which the stock is to be distributed,elevated and transported horizontally.

It is an object to provide, in connection with a stock box, a scraperextending from the botto'm of the box to engage a breast rollsubstantially on a line with the horizontal radius of the roll so thatas the sto'ck is fed onto a wire screen supported and moved thereby, thestock will be elevated and transported from the box in a substantiallyhorizontal direction.

It is also an object of the invention to provide, in connection withpaper stock feeding means, a pair of adjustable slices for regulatingthe distribution of stock upon a wire screen.

It is also anobject to provide, in connection with a stock box, rotarydrum stirrers in which the central part of each stirrer will rotate in adirection opposite the peripheral part thereof, or in the same directionat a different speed.

These and other advantages will appear from the following descriptiontaken in connection with the drawings.

Referring to the drawings:

Figure 1 is a vertical, longitudinal section through a paper makingmachine.

Figure 2 is a vertical section through the feed roll and the parts ofthe paper machine adjacent thereto, showing a modified form of drumstirrer in which the central part of each drum will move at a speeddifferent from the speed of the peripheral part.

Figure 3 shows a transverse section of the scraper.

Figure 4 is a top plan view of one side of the machine.

Figure 5 is a section on the line 55 of Figure 1.

Figure 6 is a section on the. line 6-6 of Figure 1.

The stock from which the paper is made contained in a box having afioo'r or bottom I, sides 2, a rear not shown, and a front wall 3,adjustably supported between the side walls, which are held in properposition with relation to the front wall by means of transverse rods-2a. :The front wall is supported so thatit may be adjusted forwardly andrearwardly to a limited extent by means of screws 4, one at each side ofthe box operated by a hand wheel 5 and supported by a bracket 6extending inwardly from the side wall.

Extending across from one side wall to the other is a shaft 1, suitablysupported at its ends on some fixed part of the front wall. This shaftis provided at each end, adjacent the side wall, with a gear 8surrounding the shaft and projecting into a pocket 9 formed in the frontwall. The 10 gear 8 meshes with a vertically disposed worm l0, which hason its upper end a handle I l by which the worm is rotated for rotationon the shaft 1. On the shaft 7 there is a plurality of eccentrics l2around which there is a loop mem- 15 her [3, which has extendingtherefrom a threaded shaft I4. Each eccentric projects into a pocketformed in the front wall, similar to the pocket 9 and likewisedesignated by the numeral 9.

There is also supported by the front wall a shaft 20 I5 for each shaftI4 and connected thereto by a threaded sleeve l6, which is rotated by ahand wheel II. By means of the hand wheels ll the shafts l4 and I5 maybe adjusted with relation to each other. The lower ends of the shafts i55 have thereon a slice l8. This slice extends transversely of a wirenetting 23 supported on a breast roll 20 at one end of the wire netting,while the other end of the wire netting is supported by a similar roll,not shown. For the purpose of hold- 3o ing the shafts IS in properrelation to the front wall there is provided for each shaft I5 a clampmember l9, in the form of a bolt with a nut thereon. The breast roll 20is supported by means of a shaft 2| on a frame 22. .The wire netting is35 supported adjacent the breast roll 20 by means of a plurality of tuberollers 24 suitably supported in bearings provided therefor in the frame22.

Between the front edge of the fioor of the stock box and the breast rollis a space filled 40 by means of a scraper 25,,composed of rubber with ametal plate 26 embedded therein to give to the scraper proper rigidity.The front part 21 of the scraper has no metal plate therein and engagesthe wire netting on the breast roll in 45 substantially horizontalalignment with the hori-- zontal radius of the breast roll.

As this breast roll rotates clockwise the scraper cleans the surface ofthe wire supported and moved thereby, and also provides a slight pocket50 so that the amount of surface of the wire in contact with the stockis increased, and also so that any wearon the edge of the scraper iscompensated by a tendency of the edge of the scraper to move upwardly,due to the rotation 55 of the breast roll and the movement of the wirescreen thereon. By this means there is assured a close engagementbetween the scraper and the wire netting on the breast roll. f

In the stock box is a plurality of stirring drum 28. These drums 28 haveholes 29 in the peripheries thereof, and the drums are supported bymeans of radially disposed plates 30 on an axle 32. Each radiallydisposed plate has therein a plurality of holes 3| so that the stock maypass through the holes and be thoroughly stirred and agitated.

In the form shown in Figure 2 the drums and the radially disposed platesare supported on the shafts so they may rotate at different speeds, orthe plates may rotate in a direction opposite to that of the peripheryof the drum. In this,

form the independently rotated radial plates are indicated by thenumeral 33 and have holes 34 therein through which the stock may passfor the purpose of being agitated. These plates are supported forrotation on the shafts by means of hubs 35. In front of the front wallis a second auxiliary stock chamber formed by side walls 36 and a frontwall 31, which does not extend all the way to the wire netting.

There is provided a transversely extending shaft 38 supported by meansof loops 39 on standards 48. 4| for receiving a bolt 42 by which theloops may be adjusted longitudinally of the paper machine so that theshaft 38 may be adjusted. To one end of the shaft. 38 is attached oneend of an arm 43. The other end of this arm may be adjusted by means ofa shaft 44 provided with a hand wheel 45 for that purpose. By operatingthe shaft 44 the arm 43 is moved atone end so that the shaft 38 willrock or rotate on its supports. It is to be understood that there'may betwo of these arms, one at each end of the shaft 38.

To this shaft 38 there is attached a plurality of arms 46, each armbeing attached at one end to the shaft while its other end is connectedto an angle iron 41 in any suitable manner. These arms 46 and the angleiron attached thereto support the rear end of an apron 48, which isattached at its front edge 49 to some suitable part of the shaft 38 bymeans of stay bolts 50. Each of these bolts is attached at one end tothe rear of the apron, while its other end is connected to the angleiron by means of nuts 5|.

Extending downwardly from the rear end of the apron is a plate 52, whichhas on its upper edge a plate 53 adapted to engage the lower edge of thefront wall 31. Just in front of the plate 52 and extending downwardlyfrom the rear end of the apron to a point slightly below the lower edgeof the plate 52 is a slice 54. Thev stay bolts 50, the plate 52 and therear end of the apron are joined by means of plates 55 and atransversely extending rod 56.

Extending from the scraper 25 along the periphery of the breast roll,and forwardly along the top of the wire screen at each edge thereof, isa guide 51 adapted to guide the stock as it moves forwardly on the wirescreen. These guides terminate adjacent deckel straps 58, one at eachedge of the wire screen and supported by rollers 58. These rollers aresupported and operated in any suitable manner. The slices may beadjusted independently of each other. The slice immediately above thebreast roll may be adjusted from end to end by means of the hand Theloops 39 have in each end a slot wheels l1, and it may be adjusted as awhole by means of the eccentrics on the shaft 1.

The slice 54 may be adjusted independently of the slice l8. In operationthe slice 54 is usually spaced from the wire netting a shorter distancethan the slice l8, but the slice 54 may be elevated out of operativeposition so it can be used. By means of the slice 54 and the side walls35 there is provided an additional stock box in which the stock mayaccumulate between the two walls.
